7 Claims. (Cl. 137-104) This invention relates to a supply fixture andmore particularly the valve structure thereof and for toilet storagetanks.

This application is a division of the copending application, Serial No.-284,432, filed July 14, 1939,

and entitled "Antisiphon, nonsplashing valve structure, and now PatentNo. 2,229,601, granted Jan. 21, 1941.

The chief object of this invention is to provide a toilet storage tankfixture wherein the valve is of packless character and so arranged thatit is substantially free from leakage, and especially free fromsplashing and squirting commonly characteristic of so-called packlessvalves.

The chief feature of this invention is to provide a valve structurearranged whereby water discharged under pressure creates a suction whichis so associated with the packless valve member that leakage, asaforesaid, is eliminated and thus spraying or splashing of the storagetank cover does not occur.

Another feature of the invention is that a valve of this character shutsoff at higher pressures than valves of this common characteristicemploy.

Other objects and features of the invention will be set forth more fullyhereinafter.

The full nature of the invention will be understood from theaccompanying drawing, the following description and claims:

In the drawing, Fig. 1 is a front elevational view of the embodiment ofthe invention in association with a toilet tank arrangement, the latterbeing-shown in section and with cover removed.

Fig. 2 is an enlarged central sectional view of the invention andassociated fixture parts.

Fig. 3 is a top plan view thereof.

In the drawing, l0 indicates a toilet storage tank. A pressure supplyline II is suitably connected as at l2 to a riser structure 3, thelatter extending through the tank l0 and being suitably sealed theretoas indicated at I3a. The upper end of the riser l3, see Fig. 2, isthreaded as at I4 to receive a member l5 having an externally threadedportion l6 and a nozzle portion H, the latter terminating in a suitablyformed end portion l8 which defines a discharge passage I9 that extendsthrough the member l5 and'is in free communication with the riser l3.

A body portion 2|! having a chamber 2| adjacent the discharge nozzle l8and surrounding the upwardly extending portion ll of the member I5 hasthreaded connection as at 22 with the 65 threaded portion l6 of themember is. This constitutes the support for the supply and controlfixture.

The chamber 2| communicates with a superposed chamber 23 also formed inthe member 20 and by means of a tapered passage 24. The up- 5 per end ofthe chamber 23 is closed by a plug or closure 25 having threadedengagement with the upper portion of the body casting and in axialalignment with the above described parts. This closure 25 terminates atits lower end ina frustol0 conical, preferably complementarily formedvportion 21. The seat 24 and valve portion 21, when properly spacedapart, provide a conically directed channel, providing a communicationof regulated amount -between the chamber 2| and 15 the chamber 23, theregulation being obtainable as now set forth.

The outer end of the closure 25,-integral with the control valve 21, isprovided with a lateral flange 28. The body portion includes a project-20 ing flange 23, see Fig. 2, apertured as at 30 to receive a retainingbolt 3|, thehead of which overlies the flange 28 of the valve andclosure member. This member 25-21 constitutes a closure for the chamber23 together with a valve 25 member for controlling the communicationbetween the chambers 2| and 23.

The member 25 has a bore 32 therein. This is of cylindrical characterand slidably mounted therein is a valve member which is of packless 30character. This valve member is of multi-part character. It includes ahead portion 33 and a stem portion 35, the lower end of which isenlarged as at 35a. The stem and head portions have a threadedconnection 33a therebetween, 35 see Fig. 2. The enlargement 35a isexternally threaded as at 36 to receive a threaded sleeve 31 having aninwardly tapered flange 38. Between the body portion 2|]. 50

Included within said upwardly, and laterally directed portion 48 is asupply passage 49 which, at its lower end, communicates with the chamber23 as shownin- Fig.2. The body portion of the member 25 herein is shownprovided with ports I at It, the two ring or washer-like members beingpositioned in spaced relation and forming therebetween a chamber OIwithin the bore 32.

-The stem portion 35 oi the plunger is slidably supported in theapertures 02 and It, the ring members II and 03 being press fitted intothe bore 32 and being relatively rigid'therewith.

I Now, when the lever 44 is actuated to elevate the plunger structurewater under pressure discharges fmm the e it into the chamber 16 II. Themajority of the water then discharg through the conical passage into thechamber 23 and then discharges upwardly through the passage I. Some ofthe water under pressure in chamber 2| will pass upwardly between thesleeve 31 and into the bore 32; and from thence it will pass through thelowermost ring member at the aperture 02 and into the bore chamber ll.Such water as does pass into this chamber 0 due to the discharge ofwater through passage ll is subject to suction applied to the ports IIand thus the chamber 95 is a region of low pressure instead of being aregion of high pressure such as chamber 2i. Consequently, little if any,water will discharge through the aperture 04 below the enlarged portionor head 33 of the plunger structure and within the member ll.

' Thus, the water will not spray or squirt upwardly because in mostinstances there will be no escape of water into this chamber lastmentioned 35 and such that does or may escape will be undersubstantially little or no pressure and should any escape under slightpressure, it will immediately flow along the stem portion II and engagethe under-face of the head 33 and thus be bailled or laterally directed.

The upper and remoteend of the passage I communicates with a chamber illformed in an enlargement 5| integral with the upwardly directed portionI! of the body casting. Projecting fromthe enlargement ii is a pair ofears I! and the same pivotally support as at it a lever 55. This leverterminates in a threaded socket 58 adapted to receive an arm I! in theform of a rod, or the like, that threadedly supports a float 58. Thelever between the connection 56 and the pivotal support 54 is connectedto a dual link structure so connected together as at 60. This linkstructure is pivotally connected to the float mechanism as at I and ispivotally 55 connected as at 62 to an outer free end of the lever 44. i

Extending outwardly from the chamber II is a tubular portion "-see Fig.1which supports a tube 64 that discharges into the overflow pipe 65common to all toilet storage tanks. This overflow pipe discharges to theconduit 06 below the 'usual 'manual control "ball valve. The conduit 68communicates freely with an intake structure fixture i1 normally. Thisfixture 61 65 is maintained in closed position by the rubber ball-likevalve 68 carried by the lower end of the rod 69, slidably supported inthe guide ll adjustably supported on the overflow pipe discharges to theconduit 06 below the usual manual 70 control ball valve. The conduit flcommunicates freely with an intake structure fixture I normally. Thisfixture I1 is maintained in closed position by the rubber ball-likevalve 08 carried by the lower end of the rod II, slidably I supported inthe guide 10 adjustably supported on the overflow tube II as at H. Anactuating. mechanism of conventional ,charactercommon to structures ofthis general type,.includes the lifter member I! and the head portion Itof the rod ll bears on the lateral portion of said lifter 5 member.

It will be noted that as long as water is being supplied to the chamber28 in regulated amount by means of the adjustment previously mentioned,water will discharge into the chamber I 10 and a relatively small amountof this water will discharge through tube It into the overfiow tube 6!and thence to the line It.

After the tank has been filled to the level indlcated by the dotted linedetermined by float 16 valve adjustment and the manual member isoperated, the rubber ball valve is is elevated and the water dischargesfrom the tank into the toilet bowl proper and flushes the bowl. In theevent suchflushing syphons the water out of 20 the trap normally beyondor included in the bowl, the waterdischarged by line 64 into theoverflow 05 upon closure of the valve 68, supplies water tothe bowl andespecially the trap portion thereof to water seal the same. This 25prevents the venting to the bowl of the undesirable odors that might bepresent in the waste pipepr line from the toilet fixture.

Another protective feature of the present invention is as follows:Should the pressure in the 80 1 supply line It be sufliciently greatinco-relation to the degree of opening between the conical member 2! andthe seat 21 there is created a considerable degree of vacuum in thechamber OI so that air is drawn into the chamber through so the apertureN. g 1
